Design of achromatic and apochromatic plastic micro-objectives
TL;DR: It is shown that achievable optical performance of achromatic and apochromatic micro-objectives with plastic lenses satisfy the qualifying standards for cell-phone objectives and closed-circuit television (CCTV) cameras.

Comparison of electromagnetic and scalar methods for evaluation of efficiency of diffractive lenses for wide spectral bandwidth
TL;DR: In this paper, the authors determined the microstructure conditions under which the diffractive lens, a part of the wide-spectral optical system, exhibits the highest diffraction efficiency using both electromagnetic and scalar methods.
31
Diffractive-refractive hybrid corrector for achro- and apochromatic corrections of optical systems.
TL;DR: The possibility is shown of achro- and apochromatic correction of an optical system with any residual chromatism by completing the system with a diffractive-refractive hybrid corrector comprising one diffractive lens and one or two refractive lenses.

Design of plastic diffractive–refractive compact zoom lenses for visible–near-IR spectrum
TL;DR: The efficiency of the suggested techniques of the optical layout process are demonstrated by using the example of the design and analysis of a zoom lens intended for use in security cameras for day or night vision.

Spectral and Angular Dependences of the Efficiency of Relief-Phase Diffractive Lenses with Two- and Three-Layer Microstructures
TL;DR: In this paper, the efficiency of diffractive lenses with two-layer singlerelief and three-layer double-relief microstructures is studied using the scalar and electromagnetic diffraction theories.
